Step 1

In a 6- or 8-quart pot, heat the oil over medium heat and add the onions and carrots. Cover the pot and cook/sweat the mixture, stirring occasionally, until the vegetables are tender, 3-4 minutes. Add the garlic and cook, stirring constantly, for about 30 seconds.

Step 2

Add the broth, crushed tomatoes, basil, oregano, thyme, salt and pepper. Bring the mixture to a simmer and add the tortellini. Cook for 2-3 minutes until the tortellini are mostly tender (they'll continue to cook for a few minutes in the next step).

Step 3

Whisk or blend the flour and milk together until smooth and add it to the soup, stirring constantly. Add the beans, chicken and spinach. Bring the soup to a low simmer and cook for 3-4 minutes, stirring occasionally, until slightly thickened and all the ingredients are heated through and the tortellini are tender.

Step 4

Serve with freshly grated Parmesan cheese on top, if desired.
